Technical Field
[0001] This utility model relates to the field of spring wire technology, specifically a spring wire for robots. Background Technology
[0002] Robot spring wire is a highly flexible connection cable designed specifically to meet the dynamic motion requirements of robots. It can maintain stable electrical connection and signal transmission performance during frequent bending, twisting, or extension of robot joints, while also possessing excellent fatigue resistance, wear resistance, and anti-interference capabilities, thereby ensuring long-term reliable operation of robots under complex working conditions.
[0003] Although existing spring wires have rubber sleeves installed at the bending sections of the springs to enhance protection and effectively resist bending friction and stress impact, the rubber sleeves are fixed in design and lack the ability to move flexibly along the spring wire axis. As a result, the same rubber sleeve can only be adapted to specific bending positions and cannot be adjusted according to the dynamic changes of the bending points during the actual movement of the robot, thus limiting the comprehensiveness and adaptability of its protective effect.
[0004] Therefore, we propose a spring wire for robots. Utility Model Content
[0005] The purpose of this invention is to provide a spring wire for robots to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring wire for robots, comprising: A spring wire body, wherein a guide rod is provided on one side of the spring wire body; A connecting mechanism, the connecting mechanism including a fixed base, the fixed bases being fixedly connected to both ends of the spring wire body, and a fixed ring being fixedly connected to the outside of the fixed base; An adjustment mechanism is provided, which includes a moving groove. The moving groove is provided on the outer side of the guide rod, and a moving block is slidably installed inside the moving groove.
[0007] Preferably, the connecting mechanism further includes a movable groove. The movable groove is formed on the outer side of the fixed ring, and a movable block is slidably installed inside the movable groove. A connecting block is fixedly connected to the front end of the movable block, and a rotating rod is rotatably installed at the front end of the connecting block. Locking rings are symmetrically fixedly connected to the outer side of the rotating rod. The movable groove on the fixed ring on the outer side of the fixed base allows the movable block to slide along it. This design enables the connecting block to drive the rotating rod to adjust its position within a certain range to adapt to different installation space layouts.
[0008] Preferably, a connecting seat is fixedly connected to the front end of the locking ring, and a locking hole is provided inside the connecting seat. A locking rod is installed inside one of the locking holes. The rotating rod can rotate relative to the connecting block, and in conjunction with the sliding of the movable block, the locking ring and the connecting seat at the front end can flexibly change their positions. When the connecting seat is connected to an external mechanical interface, the interface position can be precisely aligned by rotating the rotating rod and sliding the movable block. Then, the locking rod is inserted into the locking hole of the connecting seat to complete the connection and fixation.
[0009] Preferably, the fixing base has a through hole inside.
[0010] Preferably, the adjusting mechanism further includes a movable plate, with the movable plate fixedly connected to the front end of the movable block. The movable plate has a first sliding groove and a second sliding groove symmetrically formed inside each of the first and second sliding grooves. Sliding blocks are slidably installed inside the first and second sliding grooves. A support plate is fixedly connected to the front end of each sliding block, and an arc-shaped plate is fixedly connected to the other end of the support plate. Insert rods are symmetrically fixedly connected to the top of the arc-shaped plate. The movable block drives the movable plate to move synchronously. The first and second sliding grooves on the movable plate provide a lateral sliding path for the sliding blocks, allowing the sliding blocks to flexibly change the lateral position of the support plate and the arc-shaped plate. The insert rods at the top of the arc-shaped plate precisely engage with the opening of the connecting cylinder on the outer rubber sleeve of the spring wire body.
[0011] Preferably, a rubber sleeve is installed on the outer side of the spring wire body, and connecting cylinders are fixedly connected to the outer side of the rubber sleeve at equal intervals, with an opening inside the connecting cylinder for connecting the insertion rod. When the robot's movement causes the bending point of the spring wire to change, the axial position of the moving plate is adjusted by sliding the moving block, and at the same time, the sliding block changes the lateral position of the arc plate, so that the insertion rod drives the rubber sleeve to move flexibly along the axial direction of the spring wire body.
[0012] Compared with the prior art, the beneficial effects of this utility model are: Enhancing connectivity and stability: In the connection mechanism, the movable groove of the fixed ring allows the movable block to slide, and the rotating rod can rotate relative to the connecting block, enabling the connecting seat and locking ring to flexibly adjust their orientation and precisely match the complex spatial layout and angular requirements of the robot's mechanical interface. This flexible adjustment effectively avoids excessive cable twisting or pulling caused by installation angle deviations, significantly reduces mechanical stress at the connection point, minimizes signal transmission losses, and ensures long-term stability of the electrical connection.
[0013] The protective area can be dynamically adjusted: the adjustment mechanism moves the arc-shaped plate and the insertion rod flexibly by sliding the moving block along the guide rod's moving groove and the sliding block within the moving plate's sliding groove, thereby driving the rubber sleeve to change position along the axial direction of the spring wire body. This design overcomes the limitation of traditional fixed rubber sleeves that can only adapt to specific bending positions. It can adjust the protective area in real time according to the dynamic changes of the bending point during robot movement, avoiding excessive wear caused by insufficient protection in certain areas due to long-term fixed installation, extending the service life of the spring wire, and enhancing its fatigue resistance and wear resistance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 A type of spring wire for robots, comprising: Spring wire body 1, with a guide rod 2 provided on one side of the spring wire body 1; The connecting mechanism includes a fixed base 3, with fixed base 3 fixedly connected to both ends of the spring wire body 1, and a fixed ring 4 fixedly connected to the outside of the fixed base 3; The adjustment mechanism includes a moving groove 14. The moving groove 14 is provided on the outer side of the guide rod 2, and a moving block 15 is slidably installed inside the moving groove 14.
[0018] Please see Figure 2-3 The connecting mechanism also includes a movable groove 5. A movable groove 5 is provided on the outer side of the fixed ring 4. A movable block 6 is slidably installed inside the movable groove 5. A connecting block 7 is fixedly connected to the front end of the movable block 6. A rotating rod 8 is rotatably installed on the front end of the connecting block 7. Locking rings 9 are symmetrically fixedly connected to the outer side of the rotating rod 8. The movable groove 5 on the fixed ring 4 on the outer side of the fixed base 3 allows the movable block 6 to slide along it. This design enables the connecting block 7 to drive the rotating rod 8 to adjust its position within a certain range to adapt to different installation space layouts.
[0019] Please see Figure 2-3 The locking ring 9 is fixedly connected to a connecting seat 10 at its front end. The connecting seat 10 has a locking hole 11 inside, and a locking rod 12 is installed inside one of the locking holes 11. The rotating rod 8 can rotate relative to the connecting block 7. With the sliding of the movable block 6, the locking ring 9 and the connecting seat 10 at the front end can flexibly change their positions. When the connecting seat 10 is connected to an external mechanical interface, the interface position can be accurately aligned by rotating the rotating rod 8 and sliding the movable block 6. Then, the locking rod 12 is inserted into the locking hole 11 of the connecting seat 10 to complete the connection and fixation.
[0020] Please see Figure 3 The fixing base 3 has a through hole 13 inside.
[0021] Please see Figure 4 The adjustment mechanism further includes a movable plate 16. The movable plate 16 is fixedly connected to the front end of the movable block 15. The movable plate 16 has a first sliding groove 17 and a second sliding groove 18 symmetrically formed inside. Sliding blocks 19 are slidably installed inside the first sliding groove 17 and the second sliding groove 18. A support plate 20 is fixedly connected to the front end of the sliding block 19. An arc-shaped plate 21 is fixedly connected to the other end of the support plate 20. Insert rods 22 are symmetrically fixedly connected to the top of the arc-shaped plate 21. The movable block 15 drives the movable plate 16 to move synchronously. The first sliding groove 17 and the second sliding groove 18 on the movable plate 16 provide a lateral sliding path for the sliding block 19, allowing the sliding block 19 to flexibly change the lateral position of the support plate 20 and the arc-shaped plate 21. The insert rods 22 at the top of the arc-shaped plate 21 are precisely matched with the opening of the connecting cylinder 24 on the outer rubber sleeve 23 of the spring wire body 1.
[0022] Please see Figure 4A rubber sleeve 23 is installed on the outer side of the spring wire body 1. Connecting cylinders 24 are fixedly connected to the outer side of the rubber sleeve 23 at equal intervals, and the connecting cylinders 24 have openings for connecting the insertion rod 22. When the robot's movement causes the bending point of the spring wire to change, the axial position of the moving plate 16 is adjusted by sliding the moving block 15, and at the same time, the lateral position of the arc plate 21 is changed by sliding the sliding block 19, so that the insertion rod 22 drives the rubber sleeve 23 to move flexibly along the axial direction of the spring wire body 1.
[0023] Working principle: In the connection link, the fixed seats 3 at both ends of the spring wire body 1 provide a stable foundation for the connection mechanism. The movable groove 5 opened on the fixed ring 4 on the outside of the fixed seat 3 allows the movable block 6 to slide along it. This design enables the connecting block 7 to drive the rotating rod 8 to adjust its position within a certain range to adapt to different installation space layouts. The rotating rod 8 can rotate relative to the connecting block 7. With the sliding of the movable block 6, the locking ring 9 at the front end and the connecting seat 10 can flexibly change their positions. When the connecting seat 10 is connected to the external mechanical interface, the interface position can be accurately aligned by rotating the rotating rod 8 and sliding the movable block 6. Then, the locking rod 12 is inserted into the locking hole 11 of the connecting seat 10 to complete the connection and fixation. This effectively avoids excessive twisting or pulling of the cable due to the installation angle deviation, reduces the mechanical stress at the connection, and ensures the stability of signal transmission. The through hole 13 inside the fixed seat 3 provides a channel for the cable to pass through, ensuring the continuity of the electrical connection. During the protection adjustment stage, the adjustment mechanism adjusts the overall position by sliding the moving block 15 along the moving groove 14 of the guide rod 2. After the guide rod 2 is adjusted, it can be taken out along with the related parts. The moving block 15 drives the moving plate 16 to move synchronously. The first sliding groove 17 and the second sliding groove 18 on the moving plate 16 provide a lateral sliding path for the sliding block 19, so that the sliding block 19 drives the support plate 20 and the arc plate 21 to flexibly change their lateral positions. The insertion rod 22 at the top of the arc plate 21 precisely matches the opening of the connecting cylinder 24 on the outer rubber sleeve 23 of the spring wire body 1. When the robot's movement causes the bending point of the spring wire to change, the axial position of the moving plate 16 is adjusted by the sliding moving block 15, and at the same time, the sliding block 19 changes the lateral position of the arc plate 21, so that the insertion rod 22 drives the rubber sleeve 23 to move flexibly along the axial direction of the spring wire body 1. The rubber sleeve 23 is adjusted to the bending point and high stress area in real time, avoiding excessive local wear caused by fixed protection position, so that the rubber sleeve 23 always forms effective protection for the key area and resists bending friction and stress impact.
